v Lette/rs Patent No. 84,058, dated November 17, 1868.

IMPROVED WASHING-MACHINE.

The Schedule referred to in these Letters Patent and making part of thedame.

To all whom it ma/y oonce'm Be it known that I, MORTIMER S. HARSHA, ofBatavia, in the county of Kane, and State of Illinois, have invented anew and useful Improvement-in Washing- Machines; and I do hereby declarethat the following is afnll, clear, and exact description ofthe same,reference being had to the accompanying drawings, and the letters andfigures marked thereon, which form a part of this specification, and inwhich- Figure 2 represents a detached view of the wheel A;

Figure 3, a top or plan view of my machine;

Figure 4, a vertical sectional view at the line a: in iig. 3; and

Figure 5, an end elevation of the machine. My inventio11 re1ates to thatclass of washing-machines in which the clothes are passed betweenrollers; and it consists in a no'vel device, whereby the bearings ofvthe adjustable rollers are allowed to vibrate to admit the passage ofuneven thicknesses between the rollers, as hereinafter more fullydescribed.

'To enable those skilled in the art to understand how to manufacture anduse my invention, I will describe the same with particular-ity.

The same letters of reference refer to the corresponding parts inthediiierent figures.

I make a frame, B, and corrugated rollers, C and D D, which I place insaid frame, as shown in accompanying drawings.

On the shaft' of the wheel C, I put a crank, H, and also two wheels, AA, which have their sides corrugated, or are so constructed as to form aseries of cams, and they must be so arranged on the shaft that thecompression on one wheel will be opposite the projection orelevation onthe side of the opposite wheel` 'lhey rollers D D have shafts orspindles, which extend through slots E E in the frame B, and havebearings in the pivoted pieces F, and extend out to the corrugatedwheelsg, so that, as they are revolved, they, by operating against saidspindles, give the rollers D D a constant vibrating lateral motion.

The pressure upon the surface of the rollers D, as the clothes passbetween the rollers C and D D, causes them to revolve;

'The bearings ofthe spindles I are movable, and are supported upon thesprings K, so that the roller G yields to admit of' differentthicknesses of garments passing'v between the rollers, and, at the sametime, all be subjected to pressure. And the bearings of the spindles ofthe rollers D being in the pieces F F,lwhich are pivoted at theircentres to the frame B, by the screws L L, the said rollers are not heldrigid, but any thick article coming under one ofthe rollers, raises itup, and, at the same time, by vibrating the pieces F F, presses theother roller down, and, asV the thick place passes along under the otherroller and raises it, the first roller is pressed down. By thisarrangement thick places or bunches can pass between the rollers, and,at the same time, one of the rollers D is constantly pressing upon theroller C.

In the operation of my machine, it is secured firmly in any suitable,well-known manner, in an ordinary tub, which will hold the water and theclothes to be washed.

The operator turns the crank H, and placesa garment so that it is caughtbetween the rollers C and D. As the garments are being drawn betweensaid'rollers by the rotary motion given them byturning the crank H, theyare not only pressed between the rollers, but the vibrating motion ofthe rollers D D rubs the clothes between the surfaces of the rollers Cand the rollers D D.

Having thus fully described the construction and operation of myinvention,

What I claim, and desire to secure by Letters Patent, is-

Ihe combination of the bars F F, pivoted at their y centres to the frameB., the two rollers D D, having bearings in opposite ends of saidoscillating bars F F,

the roller C, arranged beneath and between said roll-v ers I) D, and thecam-wheels A,A, all arranged and operating so as to give the rollers D Da rotating, a

longitudinal, and an oscillating motion with respect toy the roller C,

substantiallyas herein shown and set forth.
